Abstract

A quantum computer architecture employs logical qubits that are constructed from a concatenation of doubly periodic Josephson junction circuits. The series concatenation of the doubly periodic Josephson junction circuits provides exponential robustness against local noise. It is possible to perform discrete Clifford group rotations and entangling operations on the logical qubits without leaving the protected state.
